A Challenge

These two passages of code occurred within the top and bottom parts of same subroutine.
The sub was working; I was prepared to live with the repetitious code.
But then I had to create a new subroutine which significantly altered other parts of the first subroutine but kept these parts the same.
I faced the prospect of having four very similar blocks of code, rather than just two.
I didn't want to be stymied by the difference between:
```
    $week{$_}{'scheduled'}
```
and
```
    $week{'scheduled'}
```
